Roadmap

Generation 3 of the Optical Disc Archive technology was announced for early-2020 release.[1] Generation 3 increased the cartridge capacity to 5.5TB, the read speed to 375MB/s and the write speed (with verification on) to 187.5MB/s.

Media roadmap

Sony Corporation and Panasonic Corporation on announced on 10 March 2014 their cooperation in producing a new media trademarked as Archival disc. The Archival disc media[3] will be used in future Optical Disc Archive Media to achieve at least 6TB of storage.
